The theoretical pH’s below are for ammonia in pure water at 77☏. Typically, the pH of an ammonia solution will be between 11 and 12, compared with a pH of about 14 for sodium hydroxide solutions. What’s the normal pH of an ammonia solution? This is reflected in the pH’s normally encountered with solutions of ammonia. Never store solutions in a volumetric flask. ![]() Transfer the prepared solution to a clean, dry storage bottle and label it. ![]() How to prepare 1000 ml of ammonium hydroxide? To prepare 1000 mL of a 0.1 mol/L solution of Ammonium hydroxide we will need to dilute 6.73 mL of 58 % NH4OH to a final volume with deionized (distilled) water. The molecular weight of NH3 is 17 g (N=14 plus 3H=3). What is the molecular weight of ammonia solution 25%? The ammonia solution (NH3) of 25% means 25 gr NH3 in 100 ml water. Crystals of ammonium sulfate should form and will tell you that the solution is fully saturated. ![]() ![]() Heat gently to dissolve all the Ammonium Sulphate and let cool to working temperature on a magnetic stirrer. Prepare saturated solution of Ammonium Sulfate, for example ~550g made up to 1L distilled water.
